Grounding the switch
WARNING! · Correctly connecting the grounding cable is crucial to lightning protection and ESD and EMI
protection. You must connect the grounding cable correctly and reliably for the switch.
The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis ground to the earth to minimize the potential for system damage, maximize the safety at the site, and minimize EMI susceptibility of the system. Select a grounding method based on the installation environment.
NOTE: The power and grounding terminals in this section are for illustration only.
Grounding the switch by using a grounding strip
CAUTION: · Connect the grounding cable to the grounding strip in the equipment room. Do not connect it to a
fire main or lightning rod. · To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
If a grounding strip is available at the installation site, use the grounding cable provided with the switch to connect the switch to the grounding strip. Connecting the grounding cable to the chassis
1. Remove the grounding screw from the grounding hole in the chassis. 2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
screw hole. Fasten the screw. As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten the grounding screw.

Accessing the switch for the first time
Connecting the switch to a configuration terminal
The SC 3570 series switches provide a serial console for connecting to a configuration terminal. In Figure 26, the switch is connected to a configuration terminal (PC as an example) from the serial console port. Figure 26 Connecting the switch to a configuration terminal

As shown in Table 12, two types of console cables can be used for connecting the switch to a configuration terminal.

The signal pinout for a DB9-to-RJ45 console cable depends on the vendor of the cable. To avoid abnormal configuration terminal display, use a serial console cable provided by Intelbras. For more information, see Table 8. To prepare a serial console cable yourself, make sure the signal pinout for the RJ-45 connector is the same as that shown in Table 13.
Connecting a DB9-to-RJ45 console cable

CAUTION:
Follow these guidelines when you connect a DB9-to-RJ45 console cable:
· Identify the mark on the serial console port and make sure you are connecting to the correct port.
· The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end.

2. Connect the RJ-45 connector to the serial console port on the switch.

Connecting a USB-to-RJ45 console cable

IMPORTANT:
· To use a USB-to-RJ45 console cable to connect the switch to a configuration terminal, first download and install the USB-to-RJ45 console driver on the configuration terminal and then connect the USB-to-RJ45 console cable to the configuration terminal.
· If you have connected a USB-to-RJ45 console cable to the configuration terminal before driver installation, you must remove and reconnect the USB-to- RJ45 console cable to the configuration terminal.
The following installs the driver on the Windows system. To install the driver on other operating systems, see the installation guide in the driver compression package named by the corresponding operating system.
To connect the switch to the configuration terminal through a USB-to-RJ45 console cable.

Setting terminal parameters
To configure and manage the switch through the console port, you must run a terminal emulator program, such as TeraTermPro, on your configuration terminal. You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs. Configure the terminal parameters as follows: · Bits per second–9,600. · Data bits–8. · Parity–None. · Stop bits–1. · Flow control–None.
Starting the switch
Pre-start checklist
Before powering on the switch, verify the following items: · The power cord is correctly connected. · The input power voltage is as required by the switch. · The console cable is correctly connected. · The PC has started, and the terminal parameters have been correctly configured.
Powering on the switch
During the startup process, you can access Boot ROM menus to perform tasks such as software upgrade and file management. The Boot ROM interface and menu options differ with software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device. After the startup process is completed, you can access the CLI to configure the switch. For more information about the configuration commands, see the configuration guides and command references for the switch.

Setting up an IRF fabric (Stacking)
You can use Intelbras IRF technology to connect and virtualize SC 3570 switches into a large virtual switch called an “IRF fabric” for flattened network topology, and high availability, scalability, and manageability. A SC 3570 switch can set up an IRF fabric only with switches from the same switch series. All IRF member devices must run the same software image version. Make sure the software auto-update feature is enabled on all member devices.

N/A
See the IRF configuration guide for the switch series. Connect physical IRF ports on switches. All switches except the master switch automatically reboot, and the IRF fabric is established.

Planning IRF fabric setup
This section describes issues that an IRF fabric setup plan must cover.
Planning IRF fabric size and the installation site
Choose switch models and identify the number of required IRF member switches, depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of all member switches. Plan the installation site depending on your network solution, as follows: · Place all IRF member switches in one rack for centralized high-density access. · Distribute the IRF member switches in different racks to implement the ToR access solution for
a data center.
NOTE: For the maximum IRF member devices supported by the switch, see the release notes that come with the switch.
Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches in the IRF fabric. An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the CLI of the master switch. IRF member switches automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see the configuration guides and command references for the switch. Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID.

2

Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology or more reliable ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Instead, the IRF fabric changes to a daisy chain topology without interrupting network services. You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind a minimum of one physical port to it. When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch. See Table 14 for the available IRF physical ports. You can bind several IRF physical ports to an IRF port for increased bandwidth and availability. Figure 29 and Figure 30 show the topologies of an IRF fabric made up of three SC 3570 switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available. Figure 29 IRF fabric in daisy chain topology

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection scheme.
Table 14 shows the physical ports that can be used for IRF connection and the port use restrictions.

Candidate physical IRF ports
· SFP+ ports on the front panel · SFP ports
· SFP+ ports on the front panel · 10/100/1000BASE-T
autosensing Ethernet ports on the front panel

Use restrictions
· Physical ports on interface modules and the front panel can be bound to the same IRF logical interface.
· All physical ports to be bound to an IRF logical interface must have the same data rate.
· A 10/100/1000BASE-T autosensing Ethernet port or SFP port can be used as an IRF physical port only when it operates at 1 Gbps.
· A 100BASE-TX/1000BASE-T/2.5GBA SE-T autosensing Ethernet port can be used as an IRF physical port only when it operates at 2.5 Gbps.
· An SFP+ port can be used as an IRF physical port only when it operates at 10 Gbps.
· For a switch that has six SFP+ ports, use the four SFP+ ports with the highest numbers as IRF ports. For a switch that has four SFP+ ports, use the two SFP+ ports with the highest numbers as IRF ports. Using these ports as IRF ports can prevent issues such as IRF split, because IRF protocol packets from these ports can be forwarded in a queue with a higher priority.

Planning the cabling scheme
Use the following cables to connect the IRF physical ports on the switch: · 10/100/1000BASE-T autosensing Ethernet port–Category 5 or above twisted-pair cable. · 100BASE-TX/1000BASE-T/2.5GBASE-T autosensing Ethernet port–Category 5e or above
twisted-pair cable. · SFP port–GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver
module and twisted pair cable or GE SFP cable. For the available transceiver models and cables, see ports in Intelbras SC 3570 Switch Series Hardware Information and Specifications. · SFP+ port–SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available transceiver models and cables, see ports in Intelbras SC 3570 Switch Series Hardware Information and Specifications. For a short-distance IRF connection in an equipment room, use a twisted pair/SFP+/SFP cable. For a long-distance IRF connection, use transceiver modules and optical fibers.

4

The following subsections describe several Intelbras recommended IRF connection schemes by using SFP+ cables and SFP+ transceiver modules and fibers. All these schemes use a ring topology.
IMPORTANT: In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different sides, you must measure the distance between them to select an appropriate cable.
Connecting the IRF member switches in one rack Connect the IRF member switches (4 switches in this example) in a rack as shown in Figure 31. The switches in the ring topology (see Figure 32) are in the same order as connected in the rack. Figure 31 Connecting the switches in one rack

Connecting the IRF member switches in a ToR solution You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution. Figure 33 ToR cabling
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch to configure their member IDs, member priorities, and IRF port bindings. Follow these guidelines when you configure the switches: · Assign the master switch higher member priority than any other switch. · Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You
perform IRF port binding before or after connecting IRF physical ports depending on the software release. · To bind the ports on an interface module to an IRF port, you must install the interface module first. · Execute the display irf configuration command to verify the basic IRF settings. For more information about configuring basic IRF settings, see IRF configuration in the configuration guide for the switch.
Connecting the physical IRF ports
Connect the IRF member switches as planned. Wear an ESD wrist strap when you connect cables or transceiver modules and fibers. For how to connect them, see Intelbras Transceiver Modules and Network Cables Installation Guide.
Verifying the IRF fabric setup
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF ports:
1. Log in to the IRF fabric through the console port of any member switch. 2. Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the
remote network management station can reach each other. 3. Use Telnet, web, or SNMP to access the IRF fabric from the network management station.
(See the configuration guides and command references for the switch.) 4. Verify that you can manage all member switches as if they were one node. 5. Display the running status of the IRF fabric by using the commands in Table 15.
